The main Nuremberg trial ended, Winston Churchill warned of an iron curtain descending across Europe, It’s a Wonderful Life received its premiere and, at Jamaica hospital in the borough of Queens, New York, Donald John Trump was born.

It was 1946, also the birth year of George W Bush and Bill Clinton, but on Sunday the current US president celebrates his 80th birthday in a style uniquely his own. Trump will stage a night of cage fighting on the once-pristine White House south lawn as part of events marking the 250th anniversary of US independence.
